Commentary on: Ultrasonic cement removal in cement-in-cement revision total hip arthroplasty: What is the effect on the final cement-in-cement bond?

[摘要] Due to the increasing burden of total hipjoint arthroplasty,1 there will continue to bean increase in revision surgery in the coming decades, even though revisions aregradually falling as a proportion of all primary hip joint arthroplasties.2 The introduction of crosslinked polyethylene andceramic-on-ceramic bearings has markedlyreduced the revisions for loosening andlysis,3,4 which were commonly performed inthe late decades of the 20th century andearly 21st century due to wear of conventional polyethylene. Lysis was found aroundmany cemented stems, which requiredremoval of the cement prior to implantinga new prosthesis. Ultrasonic-driven tools,in conjunction with standard instrumentsto remove cement, became widely used.Although these tools were generally safe,complications have been reported.5,6However, there has been an increasing use ofcementless femoral fixation worldwide,4,7,8and therefore cement removal prior to revision is now less frequently performed.
